Title: Manufacture of single crystal thin film member
Inventor: NISHIMURA HITOSHI
IPC: H01L21/306
Filed: 1989-02-01
Abstract: PURPOSE:To improve the thin film accuracy of arbitrary film thickness by a method wherein, when a specified region is eliminated by etching, a remaining N-type conducting type epitaxial layer is subjected to wet etching. CONSTITUTION:On a P-type silicon substrate 10, an N-type silicon layer 11 is epitaxially grown; a mask 12 is formed on the almost whole surface of the silicon layer 11; a mask 13 is selectively formed on the rear of the substrate 10; after an electrode 14 is formed, the substrate 10 is electrochemically etched, and the region which is not covered by the mask 13 is eliminated. In this case, etching progresses only for the substrate 10 in accordance with voltage condition; when the N-type silicon layer 11 is exposed, etching is interrupted; the silicon layer 11 is left in the thickness before etching; then the voltage between the substrate 10 and a facing electrode 17 is turned OFF, and the silicon layer 11 is wet-etched, thereby gradually thinning the thickness, so that a thin film 18 having an arbitrary thickness can be obtained with high precision.

Title: Beam scanning antenna
Inventor: KAGOSHIMA KENICHI
IPC: H01Q19/17
Filed: 1978-03-03
Abstract: PURPOSE:To enable the radial beam of a reflex-mirror antenna to scan by externally exciting an array antenna with a phase shifter and a short piece connected to each element. CONSTITUTION:Phase shifter 5 and short piece 12 are connected to each element 4 of the array antenna. The array antenna of the constitution like this is excited spatially by the spherical exciter of a horn antenna or plane-wave exciter 10 of a horn reflector from the outside. This radio wave, received by antenna 4, is reflected by short piece 12 after passing through phase shifter 5, radiated from antenna 4 after passing through shifter 5 again and then passed through reflex mirrors 2 and 3 to form a radial beam. At this time, the radial beam direction can be scan-controlled by varying the shift of phase shifter 5. Further, phase shifter 5 is controlled electrically to attain a high-speed beam scan. Since the excitation is made by one exciter, the constitution of a feeding circuit can be simplified.
